I will fix bugs and review your python or java code like a lead engineer

A bug that "just won't die" usually isn't where you think it is. I'm a Lead Software Engineer with 13+ years of experience and an M.Sc. in Computer Science. Debugging production systems and reviewing other engineers' code is what I do every day.

What I fix:

• Crashes, exceptions, and error messages in Python or Java/Spring Boot
• - Wrong results, race conditions, memory leaks, and performance problems
• - Database issues (SQL, MongoDB, DynamoDB) and API integration failures

What a code review includes:

• Line-by-line feedback on bugs, security risks, and performance traps
• - Concrete refactoring suggestions with examples, not vague advice
• - An honest severity ranking so you know what to fix first

Every delivery includes the root cause explained in plain language, so you learn from the bug instead of paying to see it again.

How it works:

1. Send me the error, the code (repo or zip), and steps to reproduce
2. 2. I confirm scope and timeline before you order
3. 3. You get fixed code, an explanation, and verification steps

If I look at your issue and it's bigger than the package covers, I'll tell you before any money changes hands.
